Brian Wampler has alway made cracking pedals – the Tweed ’57 is no exception. It’s another pedal based around the jfet “amp emulation” technique that is frequently employed in this current era of overdrive pedal design.
Here’s the description from the Wampler website:
“Brian’s work on the Wampler Pedals Black ‘65 left him grinning. Finally, after months and months of work, he’d nailed it. A pedal that can conjure a whole realm of classic tones with a few turns of the EQ knobs; a pedal that works equally well as a dedicated overdrive inspired by great, vintage Fender® amps, or as a “preamp” or “tone shaper” that, when put at the end of your signal chain, just before your amp with the gain set low, can make any pedal before it sound and respond like you’re running it through whichever favorite amp of the time period you dial it in for. A genuinely passion-driven homage to some of history’s greatest amps! Yet that accomplishment couldn’t be the end. History, after all, goes farther back than 1965, and so does the story of great tone.
Brian Wampler is a confirmed tone fiend. He has to be, to make the kind of excellent sounding and great playing pedals Wampler Pedals is known for. He knew that his work on the Black ’65 would need to be followed up by another pedal to make the classic Fender® amplifier inspired Wampler Pedals family whole. When you go back in time, past the era that inspired the sound of the Black ‘65, you find yourself in the land of tweed, where raw, driven sounds offered guitarists new possibilities that they had never heard before, sounds that have found their way onto historic recordings. Creating a pedal that could do for the tweed amps of the mid to late 1950s what the Black ’65 does for its amps would not be an easy process, but Brian has never shied away from a challenge!
Enter the Tweed ‘57, a pedal inspired by historic Fender® amps and their magic tone, a pedal which offers a wide palette of sounds and includes several features that you’ve come to expect from Wampler Pedals as well as some surprises Brian’s cooked up just for this pedal! With a full three-band EQ voiced carefully to let you get a wide range of tones from your amp, the Tweed ‘57 is not limited to trying to achieve one particular sound. And thanks to the fantastic “Input Simulator” switch, you’ve got flexibility and control just as you’d expect on an amp from that period, with Normal, Bright, and Linked input options that cooperate with the EQ and gain adjustments to give you control that is easy to use and rewarding to play with. The pedal’s dynamic response is extraordinary, and the overdriven tone is amazing.
Play the Wampler Pedals Tweed ‘57 and you’ll understand exactly what inspired Brian to create this pedal, with a sound so characteristic and raw. Worked to perfection for his setup and yours, we bet after you experience this pedal’s historic rhythm and timeless, leaping-off-the-frets lead, you’ll be grinning, too. ”
